LIGHTNING--ARRESTER.

Specificationof Letters Patent.

Patented Oct. 22, 1907.

Application filed January 3, 1907. Serial No. 350,597.

To all whom it may concern:

Be it known that I, CLARK I. S'rooKiNo, a citizen of the United States,and a resident of Hiawatha, in the county of Brown and State of Kansas,have invented a new and Improved Lightning-Arrester, oi which thefollowing is a full, clear, and exact description.

The object of the invention is to provide a new and improved lightningarrester, which is simple, durable, compact and rigid in construction,dust and moisture proof, and arranged to insure safe passage of an arcfrom a line to the ground without danger of setting fire to surroundinginflammable material.

The inve'ntionconsists of novel features and parts described hereinafterand then claims. v

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters. of reference indicate corresponding parts in all theviews.

Figure 1 is a plan view of the improvement; Fig. 2 is an enlargedtransverse section of the same on the line 22 of Fig. l, and Fig. 3 isan enlarged longitudinal sectional elevation of the same on the line 33of Fig. 1.

On a suitably constructed base A are secured binding posts B, B, B l3"and B of which the binding posts B, B are connected with the line wires0, C, while the binding posts 13 ,13 are connected with theinstrumentwires U, i, and the binding post B is connected with theground at D. The binding posts B, B are connected with each other by alightningarrester E, and a similar lightning arrester E connects thebinding posts B and B with each other, and as both lightning arresters Eand E are alike in construction it suflices to describe but one indetail. Each lightning arrester E and E consists of a casing F,preferably of cylindrical shape and made of metal or other suitableconducting material, and within the casing F is held a conductor G ofmetal, carbon or a like conducting material, and, between the conductorG and the inner surface oi the casing F is interposed. a noncondnctor Hhaving perforations, as plainly illustrated in Figs. 2 and 3. The endsof the-casing F are closed by caps I and I of rubber or other suitableinsulating material, and on the I said caps I and I are secured metalliccontacts J, J having their inner ends in con tact with the ends of theconductor G, the outer ends of the clips being connected with bracketsK, K for engagement with a corresponding pair of binding posts 13,13 orof B, 13 Now by the pointed out in the arrangement described, a directconnection is made between the pair of binding posts B, B and B, B tocom plete the circuits; but in order not to depend entirely on thelightning arresters E and E for con uectidh between the pairs of bindingposts B, B? and B. 13 it is desirable to connect the said pair ofbinding posts with each other directly by connecting wires CEC asindicated in Figs. 2 and 3, The casings E of the two' lightningarresters E and E are engaged at their outer surfaces by the curved endsof a spring bar L secured to a binding post N attached to the base A,and connected by a contacting plate 0 with the ground binding post B"previously mentioned. Now in case lightning strikes either of the linewires C, C then the electrical energy passing by way of the bracket Kand contact plate J to the conductor G can readily pass through theperiorations inthe non-conductor H to the casing F, and from the latterbyway of the springbar L to the binding post N, plate 0', binding post13 to the ground at D. Thus the surplus electrical energy readily passesto the ground without danger to the instrument connected with the wiresC C, it being understood that the ordinary electrical energy sentthrough the line wires to the instrument readily passes through thelightuingur- Testers E and E without loss of energy owing to theinsulating material H interposed between the conducfor G and the casingF.

It will be noticed that the lightning arrest er described is very simpleand compact. in construction and is completely dust and moisture proof,as the principal parts are contained within the casing F and the saidpassage of the heavy electrical discharge can readily pass tothe groundwithout danger of setting fire to the surrounding inflammable mat crial.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent A lightning arr-ester, comprising a tubular casingofconducting material. and having caps of non-comlm-tin; material. aconnection between the casing and the ground, :1 conductor within thesaid casing, perforate tubular non-conductor int'crposcd between thesaid conductor and the said casing. :tndcontacts secured on the innerfaces of the said caps and having their ends in contact with thc ends ofthe said conductor, the outer cnds of the said (111% tact-s beingadapted for circuit connection In testimony whereof I have signed mynztme to this specification in the presence of two subscribingwitnesses.
